Description
Technical field
The present invention relates to a kind of experimental provision, particularly a kind of Ocean acidification research experiment device.
Background technology
2003, Ocean acidification (
ocean Acidification) this term appears in Nature Journal for the first time.CO in atmosphere
2volume fraction continues to raise, and causes ocean uptake CO
2the amount of (sour gas) constantly increases, and seawater pH value descends, this by Atmospheric CO
2the process that the seawater acidity that the volume fraction rising causes increases is called as Ocean acidification.Since the industrial revolution, ocean has approximately absorbed 1/3rd anthropogenic discharge's carbon dioxide, when the pH mean value of surface seawater is started from the industrial revolution 8.2 drops to current 8.1, according to Intergovernmental Panel on Climate Change (IPCC), predict, by 2100, seawater pH mean value was by the about 0.3-0.4 that therefore descend, to 7.8 or 7.9, when till that time, seawater acidity will start than the industrial revolution approximately large 100% ~ 150%.
Up to the present, about the research of Ocean acidification, also quite limit to both at home and abroad.Existing research contents shows that Ocean acidification has an immense impact on to halobiontic survival and development.Ocean acidification grows impact significantly to the sea life larva.NannA. Fangue is by having studies have shown that the especially sensitivity of oceanic invertebrate (sea urchin) larva on the impact performance of Ocean acidification.The impact research that He Shengyi grows pteria martensii embryo and early larvae by Ocean acidification shows that Ocean acidification will have a negative impact to the pteria martensii early development, affects its population structure.The halobiontic calcification process of Ocean acidification energy appreciable impact, these biologies comprise: coral polyp, mollusc, echinoderm, foram and calcification algae.S. Dupont show that by research Ocean acidification can affect the calcification of echinoderm, thereby affects its normal g and D.It is economic specieses of aquaculture that a lot of calcification biologies are arranged, as sea urchin, and sea cucumber, shellfish etc.The seawater acidifying will reduce the calcification rate of these species and make it can't normal growth, thereby mariculture industry is sustained a great loss.Ocean acidification has poisonous effect to sea life.K. E. Arnold can exert an influence to the normal homeostasis function of lobster by studies show that acidosis and hypercapnia that Ocean acidification causes.Ocean acidification can affect halobiontic physiology course.The research such as Shi finds that low pH value will reduce the ability that phytoplankton absorbs ferro element.
Ocean acidification passes through the halobiontic survival and development of impact, and then has influence on the stable of marine ecosystems, also can the mankind's marine economy be exerted an influence simultaneously.
In view of Ocean acidification causes so large harm and also relatively limited for Ocean acidification research at present both at home and abroad to marine environment, therefore need now a kind of experimental technique that can be studied Ocean acidification or experimental provision.
